Well I am misunderstood here. The manual and your answer are about commandline args of Scheme in general. I am about args specifially for the program (script). That's a big difference.
I tried to find answers on the web and in the MIT/GNU Scheme docu and in books. The existing texts (online and offline) are a great deal less informative than in other languages like C or pretty much any other language. So I have tried to find a solution by experimenting but that doesn't get me far. So I have to ask newb questions. If I ever get a hang on Scheme I would be pleased to write some tutorial.
